Ah yes the Humble Virtual Boy, Nintendo's first experiment in 3D portable gaming... until it flew too close to the sun.
The Challenge: Turn a broken Virtual Boy into a Head Set Display
1. Take apart a Virtual Boy removing it's heavy inner components
2. Add 2 small internal screens (or a single large one that can be seen by both eyes)
3. Include a head strap for "Portable Viewing"
4. Add an HDMI hookup for the screen(s)
5. Make it run off of a better battery solution
The Idea:
It's big, heavy, and broken (Really it's broken, don't mod one that actually works)
Make it into something worth using with your TV, Video Game Conoles, Blue Ray Players, PC, etc.
It would be cool for LAN Gaming as well. Forget the Monitor for your Tower, Save some weight by using this instead.
